Walking piezomotors are use four or more piezoceramic fingers which actuate in a stepping sequence to drive a workpiece in a desired direction. Between steps, sub-nanoscale actuation can be achieved. High power-off holding forces and essentially unlimited travel characterize these designs, exemplified by PI’s NEXACT and NEXLINE technologies. The usual non-magnetic and vacuum-friendly attributes apply. These have proven to be enablers in sensitive optical positioning applications where carefully established positions must be maintained with nanometer stability without power for months or years.
